I am sure by now, you have purchased lighting. What did you end up with and do you like it? Although we are now using Shimano dyno hubs and Busch Muller lighting, we use a second set of lights as a back up. In the front a Minoura LH-50 mount attached to our head tube, with a front Flea from Blackburn. (Since we tour with f/r panniers & a handlebar bags) I agree with Velo, the Planet Bike Super Flash is our preferred choice. We attach them to the rear of our helmets either via a clip or velcro strap. The height is easier for motorists to see. The main reason we keep them on in flash mode, beside increased visibility, is like yesterday, when my rear light was working intermittently. As they say, "one can never be too visible."
